Advancing the future of human-centered AI

Since March 1, 2026, Dr. Jonathan Liebers has joined the Human-AI Interaction group led by Prof. Sven Mayer at RC Trust as a postdoctoral researcher. With his background in human-computer interaction and machine learning, he further strengthens the chair’s research on intelligent, human-centered systems.

Jonathan studied Applied Computer Science – Systems Engineering at the University of Duisburg-Essen, where he completed both his Bachelor’s and Master’s degrees before earning his doctorate in the Human-Computer Interaction group. His dissertation, “Behavioral Biometrics in Extended Reality: Implicit User Authentication Through Artificial Intelligence,” explored how subtle behavioral patterns can be used to authenticate users in immersive environments. By combining artificial intelligence with behavioral biometrics, his work investigates how authentication can become both seamless and secure in extended reality applications. The research has resulted in 29 first-authored and co-authored publications, including contributions to leading venues such as ACM CHI and ACM VRST.

At RC Trust, Jonathan is now turning his attention to the next generation of intelligent systems. His research focuses on Agentic AI and implicit interactions, exploring how AI can proactively support users without requiring explicit commands. By integrating machine learning with principles from human-computer interaction, he aims to develop AI systems that act less like tools and more like collaborative partners that understand context and anticipate users’ needs.

Jonathan’s expertise complements the Human-AI Interaction group’s mission to design adaptive, human-centered technologies – from immersive environments to intelligent interactive systems. His work opens new perspectives on how AI can support people more naturally, efficiently, and securely in everyday digital interactions.
